Hi,

just resolved the issue and it's really simple...
The problem with the config value "spark.es.nodes": "http://localhost:9200/" is that the elasticsearch service runs in docker which means localhost:9200 does not mean the IP address you are trying to use. You need to explicitly add the IPv4 address of your machine instead of localhost and it will work.
